[0032] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0033] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0034] like Figures 1 to 5 An aluminum alloy door shown includes a door leaf 1, which includes a rectangular outer frame, multiple horizontal bars 15, multiple vertical bars 16, and multiple door panel units; the multiple horizontal bars 15 and the multiple vertical bars 16 are fixedly connected to the rectangular outer frame, and the rectangular outer frame, the multiple horizontal bars 15, and the multiple vertical bars 16 form multiple grid units, and the multiple door panel units are respectively installed in the multiple grid units;

[0035] The plurality of vertical bars 16 include a first aluminum alloy profile and a first decorative layer coated on the first aluminum alloy profile. The first aluminum alloy profile includes a first base portion extending in the vertical direction, a first V-shaped rib 164 protruding forward from the first base portion, and a second V-shaped rib 165 protruding rearward from the first base portion. The left and right sides of the first base portion are respectively provided with first mounting grooves 166 for mounting the door panel unit. The lengths of the first V-shaped rib 164 and the second V-shaped rib 165 both extend in the vertical direction. The V-shaped tip of the first V-shaped rib 164 is arranged forward, and the V-shaped tip of the second V-shaped rib 165 is arranged rearward.

[0036] The multiple horizontal bars 15 include a second aluminum alloy profile and a second decorative layer covered on the second aluminum alloy profile. The second aluminum alloy profile includes a second base portion whose length extends in the left-right direction, a third V-shaped rib protruding forward from the second base portion, and a fourth V-shaped rib protruding backward from the second base portion. The upper side and the lower side of the second base portion are respectively provided with second mounting grooves for mounting the door panel unit. The length of the third V-shaped rib and the length of the fourth V-shaped rib both extend in the left-right direction. The V-shaped tip of the third V-shaped rib is set forward, and the V-shaped tip of the fourth V-shaped rib is set backward.

[0037] In the above-described technical solution, by providing first V-shaped ribs 164 and second V-shaped ribs 165 on the first aluminum alloy profile, the strength and rigidity of the first aluminum alloy profile can be enhanced. Even if the width of the first aluminum alloy profile is made narrower, the strength and rigidity of the first aluminum alloy profile can still be maintained. Furthermore, first V-shaped ribs 164 and second V-shaped ribs 165 can increase the area and three-dimensional effect of the decorative surface of the first decorative layer, more fully demonstrating the decorative effect of the first decorative layer. Even if the width of the vertical bars 16 is made narrower, the decorative effect of the first decorative layer can still better meet the design requirements. In particular, when the decorative surface has texture, increasing the three-dimensional effect of the decorative surface can greatly enhance the decorative effect.

[0038] In the above-described technical solution, by providing the third and fourth V-shaped ribs on the second aluminum alloy profile, the strength and rigidity of the second aluminum alloy profile can be enhanced. Even if the width of the second aluminum alloy profile is narrow, the strength and rigidity of the second aluminum alloy profile can be maintained. Furthermore, the third and fourth V-shaped ribs increase the area and three-dimensionality of the decorative surface of the second decorative layer, further enhancing the decorative effect of the second decorative layer. Even if the width of the horizontal bar 15 is narrow, the decorative effect of the second decorative layer can still meet the design requirements. In particular, when the decorative surface has texture, the increased three-dimensionality of the decorative surface can greatly enhance the decorative effect.

[0039] In some embodiments, as Figure 5As shown, the first base portion of the first aluminum alloy profile includes a first base plate portion 161, a second base plate portion 162, and a connecting plate portion 163. The first and second base plates 161, 162 are spaced apart in the front-to-back direction, with the connecting plate portion 163 connected between the first and second base plates 161, 162. The left portion of the first base plate portion 161, the connecting plate portion 163, and the left portion of the second base plate portion 162 form a first mounting groove 166, while the right portion of the first base plate portion 161, the connecting plate portion 163, and the right portion of the second base plate portion 162 form another first mounting groove 166. A first V-shaped rib 164 is connected to the front side of the first base plate portion 161, and a second V-shaped rib 165 is connected to the rear side of the second base plate portion 162. In a specific implementation, the edge of the door panel unit is snapped into the first mounting groove 166, and the door panel unit and the first mounting groove 166 are connected using glass glue 18. Furthermore, a first protrusion 167 protruding toward the door panel unit is provided at the notch of the first mounting groove 166 . The provision of the first protrusion 167 helps to reduce the firmness of the connection of the glass 18 with glue.

[0040] In a specific implementation, in order to form a three-dimensional appearance, the left edge of the first substrate portion 161 extends to the left from the first V-shaped rib 164, the right edge of the first substrate portion 161 extends to the right from the first V-shaped rib 164, the left edge of the second substrate portion 162 extends to the left from the second V-shaped rib 165, and the right edge of the second substrate portion 162 extends to the right from the second V-shaped rib 165.

[0041] In specific implementation, the structure of the second aluminum alloy profile can be set with reference to the first aluminum alloy profile. The first aluminum alloy profile and the second aluminum alloy profile can be the same profile.

[0042] In some embodiments, the first base, the second base, the first V-shaped rib 164, the second V-shaped rib 165, the third V-shaped rib, and the fourth V-shaped rib are all hollow structures. Using a hollow structure can reduce weight and save materials.

[0043] In some embodiments, the rectangular outer frame is formed by a plurality of frames, which are a left frame 11, an upper frame 12, a right frame 13 and a lower frame 14; Figure 7As shown, multiple frames include a third aluminum alloy profile 111 and a third decorative layer coated on the third aluminum alloy profile 111. The third aluminum alloy profile 111 has an overall triangular prism-shaped structure. A third mounting groove 112 for mounting the door panel unit is provided on the inner edge of the third aluminum alloy profile 111. The above-described technical solution provides the triangular prism-shaped third aluminum alloy profile 111 with high strength and rigidity. The first and second inclined surfaces 114, 115 formed on the triangular prism-shaped third aluminum alloy profile 111 increase the decorative surface area and three-dimensional effect of the third decorative layer, further enhancing the decorative effect of the third decorative layer. Even with a narrow frame width, the decorative effect of the third decorative layer can still meet design requirements. This is particularly true when the decorative surface has texture, as the increased three-dimensional effect can significantly enhance the decorative effect. Furthermore, the appearance of the triangular prism-shaped third aluminum alloy profile 111 better matches the appearance of the horizontal bars 15 and the vertical bars 16.

[0044] In a specific implementation, the edge of the door panel unit is inserted into the third mounting groove 112, and the door panel unit and the third mounting groove 112 are connected by glass 18 glue. Furthermore, the notch of the third mounting groove 112 is provided with a second protrusion 116 protruding toward the door panel unit. The provision of the second protrusion 116 helps to reduce the connection stability of the glass 18 glue.

[0045] In some embodiments, the third aluminum alloy profile 111 is a hollow structure, that is, a cavity 113 is provided in the third aluminum alloy profile 111. The use of a hollow structure can reduce weight and save materials.

[0046] In some embodiments, the door panel unit located below the door leaf 1 among the multiple door panel units is a light shielding panel, and the door panel unit located above the door leaf 1 among the multiple door panel units is a light-transmitting panel. Using the above technical solution, the light shielding panel can ensure a certain degree of privacy, while the light-transmitting panel can ensure light transmission of the door leaf 1. As a specific example, the light shielding panel is a honeycomb aluminum panel 17, and the light-transmitting panel is glass 18.

[0047] In some embodiments, decorative strips 19 are fixedly attached to the front and rear sides of the sunshade. These strips 19 comprise a fourth aluminum alloy profile in the shape of a hollow triangular prism and a fourth decorative layer covering the fourth aluminum alloy profile. The decorative strips 19 reinforce the sunshade's structure and allow it to create a unique, stylish design.

[0048] In specific implementation, Figure 8As shown, the decorative strip 19 includes a third substrate portion 191 and a fifth V-shaped rib 192 connected to the third substrate portion 191. The fifth V-shaped rib 192 is a hollow structure. The structure of the third substrate portion 191 and the fifth V-shaped rib 192 can be similar to that of the first substrate portion 161 and the first V-shaped rib 164. Furthermore, the third substrate portion 191 can be bonded to the sunshade using structural adhesive. Third protrusions 193 are provided on both sides of the third substrate portion 191, and a groove 194 is provided between the two third protrusions 193 to accommodate the structural adhesive.

[0049] In some embodiments, the aluminum alloy door further includes a door frame 2, which includes a door frame body 21. The door frame body 21 includes a fifth aluminum alloy profile and a fifth decorative layer coated on the fifth aluminum alloy profile. The left or right side of the door leaf 1 is hinged to the door frame body 21. By adopting the above technical solution, the fifth decorative layer is provided on the door frame 2 to match the appearance of the door leaf 1.

[0050] In some embodiments, as Figure 4 and Figure 6 As shown, the door frame 2 further includes a decorative member 23 fixedly connected to the front side of the door frame body 21. The decorative member 23 covers the front side of the door frame body 21. If the front and rear walls of the aluminum alloy door have different decoration styles, the decorative member 23 can be used to match the decoration style of the front wall of the aluminum alloy door, while the door frame body 21 can be used to match the decoration style of the rear wall of the aluminum alloy door. In practice, the decorative member 23 can be attached to the door frame body 21 using a snap-fit ​​mechanism.

[0051] In some embodiments, the door frame 2 is also provided with a step portion 22 blocking the front side of the door leaf 1, and a sealing strip 24 for sealing the gap between the door leaf 1 and the door frame 2 is installed on the step portion 22. The provision of the sealing strip 24 can improve the sound insulation performance of the aluminum alloy door.

[0052] During specific implementation, a door lock 110 may also be installed on the door leaf 1 .

[0053] In specific implementation, the aluminum alloy profiles described in this application are made of aluminum alloy ingots extruded into strips, have high strength, and can provide good support. The aluminum alloy profiles can be connected by fasteners, such as self-tapping screws.

[0054] In some embodiments, the first, second, third, fourth, and fifth decorative layers are spray-coated layers. In practice, the decorative layers are formed by extruding the aluminum profile and then applying a custom-colored spray-coated surface treatment. More specifically, the spray-coated layers can be in various colors and textures, such as distressed copper, iron, and wood grain.

[0055] Distressed copper-like powder coating involves applying a special coating with a copper-like texture to non-copper profiles using electrostatic powder coating technology. This coating, after high-temperature baking, creates a copper-like appearance, including color, gloss, and texture, but it is not actually made of copper. The primary purpose of distressed copper-like powder coating is to achieve the aesthetic effect of copper while avoiding the high cost and weight associated with using real copper. Products with distressed copper-like powder coating typically offer excellent corrosion and wear resistance.

[0056] Iron-like spray coating involves applying a coating that mimics the appearance of iron to non-iron materials or surfaces where direct exposure of the iron is not desired. This process can be used to create a retro, industrial-style effect while maintaining the inherent advantages of the base material, such as its lightweight and corrosion resistance. Compared to real iron, iron-like spray coatings are more resistant to rust, require less maintenance, and offer greater variety and design possibilities in color and texture.
